Fair point, given the current situation this would benefit RTK boards
only. I have no idea if we will end up in the same boat with any other
boards, but given the current supply chain status I would expect this
(multi-sourcing) to be a way of the future. So maybe an idea we pocket
for now and deploy when we end up in this situation  with more
drivers.
